Design And Implemention Of VRTool Software Platform Based On ArcGIS Engine

With the application of virtual reality to the rising demand, there's a lot of virtual reality modeling methods and tools. These modeling methods and tools can be divided into two categories: Manual and automatic modeling method. Nowaday modeling methods are still not perfect and automatic modeling methods are short of large-scale sophisticated mapping technology in detail, and even rough. Both have not reached a very good level, so it also needs to improve.In view of the shortage of current virtual reality modeling tools in the Human-Computer Interaction Modeling, we propose a virtual reality interactive modeling method. Then we design a new modeling tool VRTool with industrial pipeline and mixed design patterns, and propose virtual reality topological model (VRTP), visual trace navigation model (VTN) and Terrain Trend Rise arithmetic (TTR). We solve the problems of data source in located coordinates, linear pace mutation, formation of complex mountains and other problems in the development of software platform. The experimental results show the reliability and validity of the modeling method, and a new thought for interaction modeling is provided to the development of VR modeling tool. We have implemented the core functions of VRTool platform, and the VRTool platform has already been used into the actual project of development. VRTool is a very good platform for practicality and convenience, and better functional completeness. It's convenient to develop a small or medium size virtual reality system, and it can greatly shorten project development cycle.
